Introduction to Zisha: Yixing Zisha pottery began in the mid-Song Dynasty (960-1270), and the most important work is the Zisha pot. Zisha teapots began to appear in large numbers in the mid-Ming Dynasty (488-1620). They pay attention to shape and practical function. They are engraved with calligraphy and painting or made of elephants, and have the author's seal. They are Yixing's unique pottery crafts. In addition to pots, the main varieties include basins, bottles, stationery, sculptures, etc.
